Step 2. Combine the can of limeade, tequila, triple sec, and lime juice in a blender. (I use the limeade can to measure the tequila and triple sec–ballpark measuring is good enough.) Give it a whirl just long enough to blend it together.
NOTE: I like my margaritas strong and tart. You may want to make some adjustments to the amount of ingredients to suit your taste.
Step 3. Fill the blender to the top with ice cubes.
